Sternum anatomy lesson: The sternum, also called breastbone, is a necktieshaped bone located in the center of the chest. In fact, the word sternum comes from a Greek word that literally means "chest."

The sternum is a flat bone located within the axial skeleton. In anatomy courses, you will typically have to identify the major parts of the sternum, as well as the important landmarks.

There are three main parts to the sternum: The manubrium, the body (gladiolus), and the xiphoid process.

These parts are named after ancient words that depict parts of a sword: the manubrium means "handle," gladiolus means "sword," and xiphoid means "straight sword."

The manubrium is the superior portion of the sternum. It has important landmarks such as the jugular notch (also called suprasternal notch), as well as the clavicular notch.

The body (or gladiolus) is a flattened portion of the sternum that contains several facets for ribs 27 to attach via costal cartilage. The point where the manubrium and body connect is called the sternal angle, or angle of Louis.

The inferior portion of the sternum is called the xiphoid process. This portion allows for the attachment of the diaphragm, as well as other important muscles. The xiphoid process is made of cartilage until around middle age, at which point it usually becomes bone.
